stainless steel tuna circle hook Material swordfish hook for longline

    The molding technology adopts automatic hydraulic system, which makes the hard material can be formed in an instant, with a special point of view, and then the moment of the latter part of the stamping forging, so that the physical characteristics of the instantaneous change. To increase the hardness, but also increase the high pressure heater elastic properties (that is, within the limit hook changes can automatically spring back to the initial state) without worry about broken hook.

     Barb process using special special angle of barb materials to produce the accumulation, the formation of similar to pyramid, long barb, thick and high hardness, with pliers, destruction, also can damage the barbed tip.

     Anticorrosive, antirust experiments using extreme destruction test, factory all adopt the high concentration of corrosive experiment, products half immersed in the midst of that part of the exposure in the air, two weeks hook without corrosion and signs of rust. After cleaning wipe, intact.
